In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm.

Nov 3, 2023 · The metacarpal bones articulate with the carpal bones with their proximal ends (bases), and with the proximal phalanges via their distal ends (heads). They are labeled with numbers 1-5 going in the radio-ulnar direction. This article will discuss the anatomy and function of the metacarpal bones.

The metacarpals are a group of bones in the human hand, between the wrist and the finger bones [1]. These bones are classified as long bones, and together, they are called the metacarpus, forming the palm of the hand [2] There are five metacarpals in each hand, with each bone being associated with a specific finger [1]:

Jan 28, 2025 · The metacarpal bones are five long bones forming the framework of the palm. They are numbered from the thumb (first metacarpal) to the little finger (fifth metacarpal). Each metacarpal consists of three main parts: the base, shaft, and head. [4]

Mar 9, 2022 · The metacarpal bones are five long bones of the hand between the carpal bones and the proximal phalanges of the hand that make up most of the palm. The metacarpal bones run from the carpus, forming the carpometacarpal joints, to the base of proximal phalanges, forming the metacarpophalangeal joints. The thumb metacarpal is shorter and thicker.

Mar 29, 2025 · The metacarpal bones are five long bones located in the palm between the carpals of the wrist and the phalanges of the fingers. They are classified as long bones as they are considerably longer than they are wide.

They are five bones that form the middle part of the skeleton of the hand. These bones lie between the proximally located carpal bones and distally positioned phalanges. The metacarpal bones are analogous to the metatarsal bones found in the foot.

Its base has two essential articular facets( with the capitate & hamate bones) and a small articular region on its two sides to articulate with the 3rd and the 5th metacarpals. Its spherical head forms a joint with the proximal phalanx of the ring finger.

Brief description: There are five metacarpal bones. In each of them, two ends and a shaft are distinguished. The proximal end forms the base of the metacarpal bone, and the distal end forms the head. On the bases are visible articular surfaces by which they connect to the corresponding bones of the distal row of carpal bones.

Apr 6, 2018 · Metacarpal bones are the intermediate skeletal structure of the hand that forms a connection between the carpal bones (wrist) and the phalanges (fingers). There are five metacarpal bones, numbered from I to V. Each metacarpal bone is connected to the proximal phalange of the concerned finger.
